To all whom it may concern:

lie it known that I, Winner/r WARREN DnAN, a citizen of the United States, resid ing at Stamford, in the county of Fairfisld and State of Connecticut, have invented certain new and useful Improvements in Glen-- eratora'oz" which the following is specification, referen e being hadthe accem panyiug drawing.

The invention relates to new and useful improvements in generators and more particularly to a generator adapted to produce ignition current.

An object of the invention generator of tripolar core having a flux generating elemen and arranged so to :oduce "h. and therefore maximum current 5 at equal intervals.

A further object oi"- the invention is to pro vide a generator of the above character having a ,three legged core structure and. a rotating permanent magnet cooperating'therewith with a soft iron connection between the outer legs of the core, which soft irouf -con.- nection is arranged so as to form a fiuii'. path. between the poles of the magnet.

A still further object of the in caution is to provide generator of the above character wherein the soft iron iuei'uber forming the flux path also serves as a means for short cir cuiting the poles or the magnet when the same are in ineffective position to furnish flux to the generating coil.

A still further object of the invention is to provide a generator of the shore Ch. wherein said soft iron flux receiving men-n ber serves as a part of the housing fo-izthe rotating magnet.

In the drawings, which show, by way of illustration the invention:

Figure 1 is a view in longitudinal section through a generator having my improvements applied thereto.

Fig. 2 is a perspective view showing the ends of the two magnets, a pole piece between the same, and a portion or the nonmagnetic plate for joining and supporting the magnet sections and pole pieces. these parts being detached and separated.

Fig. 3 is a sectional view on the line 3---3 of Fig.

Fig. tie a view similar to Fig. l but show ing a slightly modified of f nerator.

Coune 1h th outer h u 01"? th core structure and. is L a part thereof a soft iron member rwl a flu? iath for'the flux flow more in detail to the drawings myimproved generator consists of a core structure which is shown in Fig. 1 and is preferably laminated throughout and is indicated by the numeral 1. This core structure is of the tripolar type, that is, it is formed with three le s indicated at 11, 12 and 1 1n the draw it on the The generating coil indie t l urawiugs is mounted. on the center leg and preteiaoly consists of a primary and secondary winding, as the generator is specially adapted for ignition purposes. The primary winding will be provided with the usual interrupter timed so as to breal: the circuit 0 em. The outer legs 12 and 13 are 'ed by the soft iron member 1 which a part of the core structure. This connectingn' ember is in the form of a ring. Secured to the core structure are side plates 1? and ".lhese side plates are bolted to the core structure by suitable bolts 19 which pass t rough openings t. in the core structure. A .1; in suitable hearings in the end plate... 1.? and 18 is shaft 6. Secured to this shaft a d rotating therewith is a n0nmagnc ic plate 20. Attached. to the non-mag plate 20 are two magnets 7 and 8 which Patented liter. 25., islfi.

From the she" o it W" he noted that the pole 9 1S :2, north pole, inle south pole, and these poles the centers of wired and ets rotate the pole l0 e are equally spaced, that is, the poles are disposed eighty degrees apart, As the through the turning the north pole will be the center leg 1' W hen the ports the flux flow is fro; the leg ll to the outer through the soft pole 10, When the south pole is oppos lo 11 is a reversal of l sen the pole piece 9 reaches Gated at 15 in the dmwi ws, 9 and 10 will he short one iron fi' .ceceiving member l fore, be seen that the nolee o the 1 are circa: so J the entir time when said megne eilective to furnish the m eting end -alien the e fies ought into registry with.

While I have described the core struc-' ture as laminated, it will be understood that the center leg ll. only new consist of leminetions, or the legs 11, 13 may of leminetions, While member connecting the legs 12 may he of cast llOIL in dthe drawings l h: re shown a slightly modified form of the invention wherein the magnet indicated 16' is in Way as to provide a flux path for the ll. 1, of ilJlX from one pole of the magnet three -13. the generating coil to the other; also in see 2:, Way as to short circuit the poles of the magnet such magnet is ineiiocti'vc to furnish flux to the generating coil, I

Homing thus described my invention, I claim as new and desire to secure by l'.,-ettei s Patent is: I
